Consider using PL/Scope

PL/Scope Enhancements in Oracle Database 12c Release 2 (12.2) (0 Bytes)It is simpler than parsing code.

How its work I admit that I am a beginner in the world of plsql and I told myself that it is possible to do it with regexp

it can be for example standard package, ULT_HTTP
UTL_HTTP Constants

undefined (0 Bytes)You need to set some session settings like this:

ALTER SESSION SET PLSCOPE_SETTINGS='IDENTIFIERS:ALL, STATEMENTS:ALL';

Then compile the package, and then query the dictionary tables being populated when you compile PL/SQL and have set PLSCOPE settings.
In the article I mentioned there is an example :
image.pnghere you would see that variable L_NUM and L_STR are declared on lunes 6 and 7, and that they reference the NUMBER and CHARACTER datatypes. You can modify the query in the example to filter only "VARIABLE" as TYPE; "DECLARATION" as USAGE and then get the associated REFERENCE row to get the datatype.

Poster mentioned ANY package, documentation exists only for Oracle provided packages.
